Due to time periodic characteristic of unsteady response induced by blade vibration. using frequency domain harmonic balance computation technique. with structural dynamics analysis. the unsteady flow field around oscillating blades was numerically simulated in one-way fluid-structure coupled manner. https://www.spidertattooz.com/Kiara-Sky-Gel-Polish-Pixie-Dust-0-5-oz-G554-p8987/
